CAN-HEADING MACHINE.

Specification of Letters Patent.

zatenteo. April 24, 906.

To 1/] whom it may concern:

Be it known that we, BENJAMIN ADRIANCE and Amos CALLEsoii, citizens of the United States, residing in the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Can-Head.- ing Machines; and ave do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention relates to that portion of the art of manufacturing sheet-metal vessels which has to do with the afiixing of the heads to the bodies of cans by mechanism acting to shape the metal of the body and head into a lockjoint.

The invention relates particularly to canheading machines of the kind where in one organism a plurality of cans at a time are adapted to pass through the several steps goin to make u the heading operation.

it contemp ates the productionof a machine whose construction is relatively inexpensive, simple, and durable, which is as thoroughly automatic as possible, so that the output will be materially augmented and the duties of an operator in running it will be lessened, and the act'on of which in the forming of thefseams or joints is as smooth and perfect. as may be, so that wear and tear on the machine itself is materially reduced and the quality of goods turned out improved.

in the accom anying drawings, where the inrention is fully illustrated, Figure l is a 'iew in side elevation of one form of a machine constructed in accordance with said invention, ccrta parts being removed. Fig. 2 is a top plan v iew of the machine as shown in Fig. 1. Fig. 3 is a view, partly in elevation and partly in section, of the mechanism going to make up one of the can-heading units. Fig. l is a horizontal sectional view taken on the line it w in Fig. 3. Fig. 5 a horizontal sectional View on theline LI: :1: in Fig. i. Fig. 6 is a View in side elevation of a detail, illustrating the manner in which the cans are fed into position for being operated upon. 7 is a top plan view of the holding member on which each can rests while being operated horizontal sectional view of the chute on the line 2 2 in Fig. 6, showing the arrangement of these parts as the holding member takes a can from the chute; and Figs. 11, 12, and 13 show the can and head in section at various stages of the operation.

The frame of the machine comprises a base a. and an arch I), supported by the base. The base carries a step-bearing c, on which is fast a gear (Z and in which is stopped the lower end of the main shaft e of the machine,which has an additional bearing at its upper end in the arch b. Said shaft carries a sheave f, around which and idlers g and one or two pulleys h a continuou belt 2' extends. Power for rotating shaft 6 is taken in through the other pulley h.

j is a disk having a central hub 7c resting on the stc -bearing 0 and arranged to rotate about sha t e, and Z is a spider, also arranged to rotate about shaft 6 and sustained at a definite distance above disk by a spacing-cylinder m, which is penetrated by shaft e. In the spider and disk are journaled three rotary shafts n, which are sustained against downward displacement by pinions 0, fixed on their upper ends and bearing on the top of the spider. Each pinion 0 meshes with a gear 1), fast on shaft 6. The lower end of one -of the shafts it carries a pinion g, which meshes with a pinion r, which with ano her pinion s, meshing with gear cl, is fast on a shaft 1, sn )ported by a collar u on bearing "v in the dislr Gear (Z being stationary ,while the structure comprising the disk, the spider, shafts n, the pinions which connect said shafts with pinion p, and the pinions which connect shafts n mtergeared, through gear members '0 and p. with ear d is rotary, upon rotating shaft e not on ly will the structure referred to be rotated as a whole, but each shaft a will be rotated in said structure individually, as will be manifest.

w is a post formed at mat its lower end with a flange and having its up 61 portion y reduced and secured in one of the arms of the spider bya set-screw 2. A revoluble disk 1 is supported by this flanged post, its hub portion 2 being journaled on the post between its flange and the arm of the spider. This disk these two pairs of levers are exactly alike except in a certain particular hereinafter mentioned, reference will be made specifically to but one. 4

10 is a lever fulcrumed in the disk, its fulcrum being afforded by a boss 11, formed integrally with it, and which carries a nut 12 for maintaining the lever inplace. The free end of this lever carries a roller 13, adapted to run in a groove 14, formed in the under face ofa blockv 15, which serves as the chuck portion of the mechanism which holds the can and head assembled, as hereinafter described, while undergoing the uniting operation, said groove, be it remarked, being s aped to conorm substantially to the contour of the can to be operated upon. The block 15 has a tubular spindle 16, which projects up through the post 12) and is secured 1n the same by a nut 17. Said lever, 10 and another lever 18 are pivoted together at ap roximately their middle portion, as at 19. he free end of the lever 18 carries a knurl or shaping-roller 20, while its other end carries a vertical stud 21, which projects up through an arc-shaped slot 22 in the fulcrum portion of lever 10 and. acts as a bearing at its upper end for an antifriction-roller 23.

The mechanism above described is duplicated, being marked A and B in Fig. 4, mechanism A beln exactly like mechanism B, except that the knurl 20 of, the former is shaped so as to im art the rimary bendin to the metal, as illustrated in Fig. 12, w 'le the knurl of the other, B, is shaped to bend the metal into the form shown 1n Fi 13. Levers 18 are the ones which are irectly involved in shaping the metal. Levers l0 simply serve as their supports. Levers 18 take their general direction of movement from levers 10; but the direct actuation thereof in order to shape the metal is imparted thereto from the cams 6 and 7, roller 23 of mechanism A being made to engage cam 6, while roller 23 of mechanism Bengages cam 7.

It will be observed upon a comprehensive view of the subject-matter of this present application that the mechanism above described 15 one in which the she nin means is rotatable around the work. lo hroad claim for a mechanism per se of this nature is made in the present instance,provision to that end hav- 23 are actuated by the cams 6 and 7, and so cause the movement of the levers 18. Thus while the levers 18 arerotating about the work they are caused by the cams to a proach the work or are permitted by t e cams to recede from the same.

The disk 9' carries several plungers 26, on which are mounted the can-holders 27. These are in the form shown in Figs. 6, 7, and 8, where there is a plate 28, having a flange 29 extending around one side and one end of the plate, it being separated from the plate at the end edge thereo by a slot 30: Each canholder corresponds to one of the arms of the spider Z.

On the base a is arranged a camway 31, on which roll antifriction devices 32, carried by the plungers 26. This camway acts to elevate the plungers and hold each elevated while the can is being 0 erated upon, and when the o eration on tlie can is complete it permits t plunger to fall, so that. the can may be removed.

33 is a can-feeding chute having a support 34. This chute is arranged adjacent the high part of the camway 31. One of the side walls 35 of the chute terminates short of the end thereof a distance corresponding with the width of the can, while the other wall-36' is extended aroundto form an end wall 37 on the end of the chute. This end Wall is spaced from the bottom 38 of the chute by a slot 39, corresponding to the height. of the flange 29 of the holder 27. In order to insure the cans seating squarely on the' holder, 9. spring-actuated presser 40 is pivoted on the side wall of the chute, through which the can leaves the chute, said presser acting outwardly toward the flange 29 of the holder.

41 is a plunger having a splined connection with the spindle 16, through which it extends, being normally pressed upwardly by a spring 42, takingbetween a head 43 on'the plunger and the upper end of the spindle, said head carrying an antifriction-roller. 44. Said roller is adapted to engage a fixed cam 45, carried by the arch b, when the roller 32 on the plunger 26 reaches the depression in the camway 31, the function of the plunger being to prevent the can adhering to the chuck 15.afte the holder 28 is withdrawn.

46 is an arc-shaped guide. carried by the t arch b and adapted to insure the true seating of the cans on their holders as the plungers 2t) successivel the chucks 15.

47 is a deflector projecting laterally from the chute in such manner as to cause each can as it approaches completed to be wi ed oil' its holder 27. it will be understood t at -the can-chute is incline 'l,-so that as fast as a can is removed from the end thereof another is crowded into its place. The cans 48 and their heads 49 are originally shaped as illustrated in Fig. 11, and each head, if desired, is placed in position on its can by an attendant just previously to their being withdrawn assembled from the chute to undergo the jointin; operation. Assuming that the shaft c rotates in the direction of the arrow adjacent to the same in Fig. 2, the structure comprising *the spider Z, the disk j, shafts n, journaled in said spider and disk. and the mechanism carried by said shafts and the spider and disk will be rotated hodil in the direction of the large arrow, (shown at the bottom of Fig. 2,) while the rotar parts of the units constituting the several cam-heading means proper will rotate in the same direction as indicated by the smaller arrows at the top of Fig. 2.

Regarding first the manner in which the cans are successively taken oil from the chute then held while undergoing the heading operation and then when the heading operation is rompletei'l discharged from the machine, as the structure referred to above caused to rotate around shaft e as a center each can-holder 2fs approaches the chute and courts with the end thereof in the manner clearly illustrated in Fig. 6 to take off a can. As the holder leaves the chute the proper sea ting of the canon the holder is insured by the presser 40, and when the can leaves the chute it will he understood that'the other cans are caused to slide down to place a new can in position to be taken off, owing to the incline of the chute. The can taken off be-v ing duly established on the holder, ciunwav 3; causes the plunger 36 to rise and force the.

the corresponding chuck 15, the guide .6 meantime acting to maintain the can in proper position. The can members are now shaped by the mechanism for effecting this, aswrill be later described, and remain under the action of said mechanism until the above-mentioned structure has passed :hrough a. half-revolution, or approximately so. The heading being completed, the plun- 125. which holds tne cam up against its chuck. drops down on the low part of the eemway 31 and simultaneously roller 44 engages cam 45, and so causes the depression of plunger 4i, which acts, as above stated, to cause the can to follow its holder'i. 5., to prevent its adhering to the chuck. When the plunger has reached its lowest limit of can age-i usi movement, the structure referred to will have 1 act.) nether Words, wlule the entire struc- 1 0 5' rise to force the cans against i l. l i l it i l j turned far enough so that the deflector 47 is reached, and this being, in the horizontal plane of the can wipes the same off into a suitable receptacle.

Regarding now the operation of the mechanism directly effecting the sha ing of the metal of the can and head where y to inter lock the same. in one complete revolution of the structure above referred to each disk 1 gains one revolution on the corresponding annulus 4that is to say, whatever is the number of revolutions imparted to each annulus 4 during one revolution of the entire structure the corresponding disk 1 has one more than that number of revolutions for the same interval. Fig. 4 shows certain parts of one of the can-heading units as they stand at the initiation of the shaping action. In other words, it shows the exact positions of the various parts of the extreme right-hand unit in Fig. 2. At this time the can has been securely clamped between its holder and chuck. The parts being in rotation, as the unit referred to 1s carried around with the entire structure its disk 1 gains on its annulus 4 in the man ner above stated, with the result that roller 23 of mechanism A rides u on the high part of cam 6, thus forcing the knurl up to the work. iiiv the time that the structure has completed a quarter-revolution disk 1 will 9. have gamed an annulus l one-quarter of the circumference of the latter, and it being remarked that thehigh'part of earn 6 is only ninety degrees in length roller 23 will ride down on the low part of cam 6, with there- I00 sult that knurl 20 is withdrawn from the work. Meantime it should be understood the knurl referred to has completed several revolutions around the work and leaves the joint to be formed between the can-body 48 and head'49 in the form illustrated in Fig. 12. As knurl 20 of mechanism A recedes from the work knurl 20 of mechanism B begins to en gage the work, this because its roller 23 c0mmences to ride up on the high part of its ca rn no 7 just as roller 23 of mechanism A left the high part of ts cam 6. During the next uarter-revolution of the entire structure knurl 20 of mechanism B keeps In Contact with the work, being caused to revolve sev- 1'15 oral times around the work, and when this quarter-revolution is finished the roller 23 of mechanism B runs off the high part of cam 7 and withdraws the knurl 20 from the work,

which now left in the form illustrated in 1-20 Fig. 13. Both rollers 23 of mechanisms A and B are now clear of the high parts of their respective cams, and they remain so until the entire structure revolves far enough to bring the unit being particularly referred to back to its extreme. right-hand position, Fig. 2, (so that the means for discharging the completed can and the means for thereupon deposltinga: can to be headed will have opportunity to ture is completing the second half of itscycle cam, thus permittin the corresponding knurl to stand clear 0 the work while the candischarging and can-supplying mechanisms are operating.

This machine is diflerentiated from any of which we are at present aware in at least one salient feature i. e., that the heading means as a part of a moving structure whereby the can parts are taken up at one position, j ointed, and then discharged is complete in itself. Thus, as against, say, a machine in which the cans are rotated both individually and ad a gig-{013p and are successively brought against e joint-forming tools,the resent machine has the advantage that the drivin means is only subjected to the retarding e ect of the various tools on their work and not this retarding effect plus that of the tools on the entirerotating structure as the cans are moved past the tools. This means not alone an economy of ower and a saving of sudden applications 0 load on the source of power, but an avoiding of the consequent sacrifice of smoothness in running. Again, the feature referred to makes it possible to increase the output of the machine to an extent only limited by the number of units- 5. e., as the 'units are increased so the output may be proportionately au mented.

' In a machine of the kind, for instance,

above mentioned, where each unit is not complete in itself, but has to coact with a station- I ary part or parts, there is a limit to increasmg the output for a given size of machine. This is due to the-impossibility of getting a given number of units past the 'coacting art or parts with the same ractical effects 0 o eration, as a less num er of units could fie made to operatively ass said part or parts.

Having thus fully escribed our invention, what we claim as new, and desire to secure by Letters Patent, is-
